of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, referencebeing had.

to the accompanying drawings, which form a part of this specification.

My invention is designed to provide certain new and usefulimprovementsin a land roller'; and it consists of the construction, combination, andarrangement of devices hereinafter specified and claimed, andillustrated in the accompanying drawings, in which? Figure 1 is an endelevation. Fig. 2 is a; plan View. Fig. 3 is a horizontal section-on 1the line 3 3, Fig. 2.

I carry out my invention as followsi,

A represents a main frame to which ,the tongue A is connected in anysuitable manner. necting-braces A'Zwhich braces are united by a bar Asaid bar also being engaged with the tongue in any suitable manner. Thefront and rear portions of the main frame are constructed to receive tworoller-frames B and B, which may be rectangular. These rollerframes arepivotally supported intermediate of their extremities upon the adjacentextremities of the main frame in any suitable manner,as bysupporting-pivots a,which may be secured to the extremities of the frameA, the roller-frames bein g socketed,as indicated, to receive saidpivots. The roller-fran1es B B are provided with any suitable rollers GC. These rollers are supported upon axles b,which may be engaged in anysuitable manner with the ends of the roller-frames and with the ends ofthe corresponding rollers. To the rear of the main frame I alsocontemplate 10- The main frame is provided with c'on-" eating anadditional frame to support an additional roller C said roller C beingsupported upon axles b. The rear frame B is connected with the rearportion of the main frame in any suitable manner, as by eyes 1, enteringthe respective frames, said eyes heiug connected by a link, as indicatedat b. It will be perceived by reference to Fig. 2 that the adjacentextremities of the rollers C C are spaced quite a little distance theone from the other by the intervening connecting-bar A and otherportions of the mechanism. The drag-roller 0 however, is so located asto cover said space between the' rollers C C in the operation of thedevice.

It will'be perceived that the construction above described permits theroller-frames I) B, supporting the rollers C O, to-tilt longitudinallyof the machine upon the pivot a, so that either extremity of each of therollers O O is free to tilt to conform to any unevenness of ground, aseither end of said rollers is free to tilt upward or downward, ascircumstances may require, so that the rollers may tilt into furrows andalso over stones or other impediments in the way. The drag-roller C isalso free to rock and tilt vertically and longitudinally to a suitableextent by means of the connection of the frame B with the main frame'A.The rollers may be made of any suitable material. In Figs. 5 and 6 oneof the rollers is shown having its cylinder or drum formed of suitablesheet metal, (indi cated by the numeral 2,) suitably secured at itsextremities upon a head 3. To each of these heads I prefer to secure aremovable hub 4, in which the corresponding axle is secured. The hub maybe constructed with a I flanged head, (indicated at 5,) which maybebolted to the head 3, as indicated at 6. The head 3 is preferablyrecessed to receive the head of the hub, as shown, the head being formedwith a shoulder surrounding the head of the hub, as indicated at 7. Thisshoulder about the head of the hub strengthens the union of the one withthe other. The axles b may be constructed with a flanged end or head(indicated at 8) engaged in corresponding recesses in the huh. I preferto locate the axles in the sand in casting the hub and to cast the hubabout one end of the axle. The axles may each be engaged with thecorresponding frames by means of boxes D, preferably formed of lower andupper portions 62'- and d, rabbeted together, as indicated at d Fig. 7.The boxes may be engaged with the corresponding extremities of theframes by means of a clip 6, passing thereabout and through the frameand secured therein by means of nuts 6, a plate 6 intervening betweenthe nut and the frame. T0 resist torsional strain, the upper portion ofthe box is preferably constructed with lugs (indicated at d to enter theadjacent surface of the frame.

Each axle and its box or hearing D is pro vided with ball-bearings,(indicated in Fig. 6 at F.) To this end the plates of each of thebearings are preferably constructed with annular recesses intermediateof their ends, as shown in Fig. 6, to'receive the balls, the peripheryof the axles being also preferably recessed, as shown, to engage withthe corresponding ball. I also design that the end face of the hub andthe adjacent end face of the corresponding hearing shall be grooved,

as indicated at G, to receive corresponding balls therebetween. In thismanner a double ball-bearing is provideda ball-bearing for the adjacentfaces of the hub and hearing and for the axle and the hearing. The twoportions of the bearing may be held together also by means of a suitablescrew H.

The tongue 10 is preferably constructed with an elongated slot 11 topermit the longitudinal adjustment of the seat 12 thereupon,

plate 12 as shown in Fig. 4, which plate may be secured to the adjacentframe, the axle being journaled. in the roller in any desired way. Thepivot a may be constructed also in an analogous manner. A roller'soconstructed is obviously of superior advantage and efficiency.

What I claim as my invention is-* 1. In a roller, the combination of arollerframe, a roller provided with a head; a hub provided with an axleprojecting therefrom removably engaged with said head, and a bearingformed of a lower and an upper portion to receive the opposite end ofthe axle, screws to unite said portions, and a clip to secure saidbearing underneath the adjacent extremity of said frame, the head of theroller recessed to receive the adjacent end of'the hub and provided witha flange or shoulder about the adjacent end of the hub, substantially asset forth.

2. In a roller, the combination of a rollerframe, a roller provided witha recessed head, a hub and its axle removably engaged with said recessedhead, a bearing for the opposite end of the axle formed of alower and anupper portion, screws passing through the upper portion into the lowerportion to unite said portions, a clip to engage the bearing underneaththe adjacent extremity of the frame, ball-bearings located intermediateof the ends of the hearing about the adjacent end of the axle, andadditional ball-bearings between the end face of the hub and theadjacent end face of the bearing, as set forth.

In testimony whereof I sign this specification in the presence of twowitnesses.

I ANDREW W. AOKER.
